Abstract: There is provided a system in which a transponder is carried by each vehicle traveling on or above the earth's surface which transmits a signal which is responsive to an interrogation signal to a ground station through two or more satellites and in the ground station, the position of the vehicle is determined from the propagation time differences of the response signals received via the satellites. In this system, the information indicative of the time lag which is required for the transponder to receive the interrogation signal and to transmit the response signal responsive to the interrogation signal is included in the response signal and then such response signal is transmitted. Thus, the time lag which is peculiar to each transponder and corresponds to the time required from the reception of the interrogation signal to the transmission of the response signal can be corrected. With this system, the positioning accuracy of each vehicle can be improved.

Abstract: The circuit is for example a low noise amplifier for use at microwave frequencies and is fabricated using integrated circuit techniques. Critical components (L1,L2,L3,L6) are made adjustable so as to simplify the design process and manufacturability of the amplifier. The amplifier has two stages (Q1,Q2) in which TEE networks are used as input and output networks in each stage, and in which one element of each TEE includes an adjustable spiral inductor (L1,L2,L3,L6). The value of each adjustable spiral inductor may be adjusted by removal of one or more air bridges disposed along the inner turn of the inductor. This permits one to "tune" the amplifier and optimize its performance.

Abstract: A new and improved method and composi­tion for determining the presence and concentra­tion of low to trace amounts of proteins, such as albumin, in a test sample, such as urine. The method includes using a reagent composition capable of interacting with low to trace amounts of proteins to produce a visually or instrument­ally detectable and/or measurable response. The method can be used in wet assays or in dry test strip assays, wherein the reagent composition is incorporating into a carrier matrix. The new and improved reagent composition, comprising a dye, such as a polyhydroxybenzenesulfonephthalein-­type indicator, like pyrocatechol violet; a tung­state, such as ammonium tungstate; and, if neces­sary, a suitable buffer, is incorporated into the carrier matrix to provide sufficient sensi­tivity to low to trace protein levels and suffi­cient color resolution between low to trace pro­tein levels, thereby affording an accurate and trustworthy protein assay of test samples having a low protein concentration.

Abstract: An apparatus that guides an object in a straight line path of motion employing two leaf springs which lie side by side in their unflexed state in a plane perpendicular to the direction of motion of a moving part. One end of one spring is coupled to the moving part. The other end of the spring and one end of the second spring are coupled together in a free floating fashion. The second end of the second spring is coupled to the frame of the machine. As the moving part travels, the two springs bend in identical but opposite directions, canceling out any deflection or decrease in the lengths of the springs caused by the springs' flexing action. Even when the springs are flexed, they remain in a plane parallel to one another and perpendicular to the plane of the moving part. The moving part is coupled on one end to a conventional guiding device which confines the moving part to a plane parallel to the frame of the machine. The stiffness of the springs and the connection of the moving part to a guide allows the moving part to travel without any undesired tilting, and since the springs are coupled together in a free floating fashion, the moving part can travel in its straight line path without any friction.

Abstract: The invention is based on the object of improving a method and an apparatus for reducing the practical bandwidth of a band-limited signal by coding said signal in such a manner that by this means any type of signal can be processed with large reduction factors without loss of quality. 
<??>The object is achieved by the fact that an input signal present at an input (30) is multiplied by the output signal fed back in a feedback loop (34). The signal obtained by the multiplication is filtered by means of a low-pass filter (32). The signal present at the output of the low-pass filter forms the output signal which is frequency modulated in the feedback loop, amplified and frequency modulated again. 
<??>The drawing shows a block diagram for a device for reducing the practical bandwidth of a band-limited signal.

Abstract: A method and apparatus for allowing fault recovery in a digital computer based control system whereby system upsets induced by external transient noise conditions can be recovered from is disclosed. A CPU (10) is coupled to its main memory (20) and its I/O interfaces (16) by a common address/data bus (22), these three elements being susceptible to having data thereon or therein corrupted by transient noise. Also coupled to the bus, but in a hardened environment, are first and second supplemental memories (34, 36) which, under memory control (38), operate on alternating even and odd computational frames defined by the CPU's real-time clock to store the same words as are then being entered into the CPU's main memory (20). As computational frames are entered into one or the other of these two memories (34, 36) by eaves-dropping on the common bus (22), the other supplemental memory is transferring its contents to a backup memory (30) which is also housed in the noise-immune environment. The backup memory is connected in a read-only mode to the address/data bus and, because of the manner of operation, always contains the computational frame that is delayed one cycle of the CPU's real-time clock from the frame in progress. Should a transient upset occur, it may be followed by a transfer of the information from the backup memory (30) into the computer's main memory (20) such that computations can then continue with data that is uncorrupted.

Abstract: A coin validator of a static capacitance system for discerning the thickness and/or pattern of a coin (1) in a non-contact manner. A pair of electrode assemblies (2, 3) including a first and a second sensor electrodes and a first and a second guard ring electrodes are disposed on the corresponding sides of a coin path. The first and the second guard ring electrodes prevent the dispersion of the electric lines of force generated by the first and the second sensor electrodes. The sensor electrodes are impressed with resonating output signals from resonators (7, 8). Under such condition, when the coin (1) passes through the coin path between these electrode assemblies (2, 3), the entire inter-­electrode capacitance changes to fluctuate the resonating output signal and hence allow the thickness and/or pattern of the coin to be detected. The guard ring electrodes of the electrode assemblies (2, 3) serve to focus the electric lines of force into a beam to thereby allow the thickness of the coin (1) to be detected finely.

Abstract: An electrostatic charge pattern is formed on a charge retentive surface (10). The charge pattern comprises charged image areas and discharged background areas. The fully charged image areas are at a voltage level of approximately -500 volts and the background is at a voltage level of approximately -100 volts. A spatial portion of the image area is used to form a first image with a narrow development zone while other spatial portions are used to form other images which are distinct from the first image in some physical property such as color or magnetic state. The development is rapidly turned on and off by a combination of AC and DC electrical switching (26, 49, 50, 51, 52). Thus, high spatial resolution multi-color development in the process direction can be obtained in a single pass of the charge retentive surface through the processing stations of a copying or printing apparatus. Also, since the voltages representing all images are at the same voltage polarity unipolar toner can be employed. 
     In order to effect development of all images with a unipolar toner, each of the development system structures (32, 34) is capable of selective actuation without physical movement.
